TechnicalData Sheet C502 December -2009 PRODUCT DESCRIPTION Soldering Iron: Good results can be obtained using a range of tip C502 provides the followingproduct characteristics: temperatures. However, the optimum tip temperature and Technology Solder wire -Cored heat capacity required for a hand-solderingprocess is a Activity Medium functionof both soldering irondesign andthe nature of Product Benefits No clean the task. Clear residue Care should be exercised to avoid unnecessarily hightip Goodwetting temperatures for extensive periods oftime. Fast soldering A hightip temperature may increase any tendency to flux Mildodor spitting andit may produce some residue darkening. Pb-free and SnPballoys available The tip of the soldering iron should be properly tinned. IPC/J-STD-004 ROM1 Severely contaminated soldering iron tips should be Classification cleanedwith Multicore Tip Tinner/Cleaner. Application Soldering Wipe the tip ona clean,damp sponge before re-tinning Surface Finishes Copper ,Brass andNickel with C502 wire. Soldering Process: C502 cored solder wire has been specially formulated to 1. Apply the soldering irontip to the work surface. The iron complement noclean wave andreflow soldering processes. tip should contact both the base material andthe lead at C502 is also well suited for soldering applications requiring the same time to heat both surfaces properly. It should highmelting temperature alloys . take nomore than a fraction of a second to heat both surfaces adequately. TYPICAL PROPERTIES 2. Apply C502 flux cored wire to a part ofthe jointsurface away from the soldering iron and allow to form a joint Solder Cored Wire fillet. This will be virtually instantaneous. Do not apply Alloys -Tin/lead SN63 excessive solder to the jointas this will not improve joint SN60 integrity and it will leave excess flux residues onthe SN62 surface. Alloys -LeadFree 96SC (SAC387) 3. Remove solder from the work piece andthenremove the 97SC (SAC305) irontip. 99C(SnCu) 4. The total process will be very rapid, dependingupon 95A (SnSb) thermal mass, tip temperature, tip configuration andthe 96S (SnAg) solderability ofthe surfaces to be joined. AcidValue 156 to 172 mg KOH/g 5. The resin and flux systems are designed to leave Halide content 0.2% relatively low residues andto minimize residual activity. Flux Content(%) 2.7 This is achieved by ensuring some decomposition and volatilization takes place during the soldering process ALLOYS: The alloys used inC502 cored solder wires conform to the Cleaning: purity requirements of the common nationalandinternational C502 flux cored solder wire has been formulated to leave standards . amber flux residues and resist spitting and fuming. Inmost industrial andconsumer electronics applications, cleaning will FLUX: not be required. The product may, therefore, be used to C502 solid flux is based on modified rosin and carefully complement a no-cleanwave soldering or reflow process or to selected activators. Inpractice they exhibit a mild rosin odor allow repairs to cleanedboards without the needfor a second andleave a small quantity ofclear residue . cleaningprocess. Inhigh-reliability applications, the residues should be removed. DIRECTIONS FOR USE Soldering with C502 does not require any special methods or Should cleaningbe required, this is best achieved using deviation from standard handsoldering practices. SC-01 cleaner.
